Having sent Zak that sketch last night, I expected to go and enjoy my weekend, and probably to hear from him at some point next week about how the catch can was coming on.
When he sent me this pic at 6pm, I thought "that's good, he's started it already"
I was a bit shocked when just a few minutes later he sent me these:
Component parts:
These are the two internal baffles. The openings in each have been calculated to be just over double the CSA of the total inlets / outlets to each chamber:
The basic internal shape before the sides go on:
A few layers of mesh were added in the outlet chamber, to further diffuse any oil vapour that's made it that far
I wanted more than the usual single inlet, with 19mm feeds coming from the crank case and the cam cover, I asked for 2x 19mm inlets:
It seemed daft to vent 2x 19mm inlets through a single 19mm outlet, so the outlet size was bumped up to 25mm to really help it breath freely:
At this point, the top went on:
Pretty incredible welding on this!
Zak asked me if I wanted a drain, or a sump return on the can, at some point I may consider a sump return, but for now I just wanted a drain, so Zak added a threads stub that I can use for a drain in future, and onto that he fitted a neat little drain tap:
All that was left was 2 brackets to allow me to mount it via Riv nuts to the inner wing, and it was finished!
I've not seen it in the metal yet, as these are pics Zak sent me this evening when he made it, but from the pics it looks very good indeed, and sxacty what I had in mind.
More pics to follow and installation once it's in my hands next week
